Why clean photoelectric sensors?

There are three photoelectric sensors on M1, corresponding to X-axis, Y-axis and Z-axis respectively. When the machine returns to the origin, the position information is detected by the photoelectric sensor to realise the machine reset. When the M1 is laser processed, a certain amount of smoke will be generated, and the smoke will adhere to these photoelectric sensors. After a long time, the photoelectric sensors may fail and cause a reset failure. Therefore, when the error code of reset failure occurs(Qx14 1、Qx14 2、Qx14 3), the corresponding photoelectric sensor can be cleaned first to eliminate the fault.

Required tools

  • Cotton swabs;

  • Alcohol;

  • Phillips screwdriver;

1. Cleaning the X-axis photosensor(Qx14 1)

Insert the cotton swab into the hole on the left side of the laser head assembly, and turn the cotton swab left and right to wipe the X-axis photoelectric sensor. If there is a lot of dirt, use a cotton swab dipped in a little alcohol to wipe it.

  3. Use a cotton swab to gently wipe the Y-axis photoelectric sensor. If there is a lot of dirt, you can use a cotton swab dipped in a little alcohol to wipe it;m4.jpg

 

3. Cleaning the Z-axis photoelectric sensor(Qx14 3)

  1. Refer to the video in the following link to remove the metal cover and laser fan on the laser head assembly: https://support.xtool.com/hc/en-us/articles/5933587993879-How-to-Replace-the-Z-axis-Adapter-Board-for-M1

  2. Gently lift the Z-axis adapter plate, and then use a cotton swab to gently wipe the Z-axis photoelectric sensor. If there is a lot of dirt, you can use a cotton swab dipped in a little alcohol to wipe it.m5.jpg

     
    1. Follow the tutorial in the previous video to reinstall the laser head assembly.
